WILMINGTON, Mass. — Boston Bruins general manager Peter Chiarelli and a number of his Boston Bruins players might not have been able to believe their eyes. But the number on the sheet didn’t lie.

After his players went through their off-ice testing on the first day of training camp at Ristuccia Arena, Chiarelli confirmed that captain Zdeno Chara did 31 pull-ups. Obviously, his strength is already in midseason form.

Overall both Chiarelli and head coach Claude Julien said they were content with the testing, although they hadn’t scrutinized all the results yet.

•With the first two on-ice sessions of camp scheduled for tomorrow at TD Bank Garden, Chiarelli offered an update on some of the players’ injuries. Winger Marco Sturm, who had season-ending knee surgery last winter, and defenseman Andrew Ference (groin and hernia offseason surgery) are able to go through full practices. Needless to say, Sturm is eager for the activity.

“I’m going practice like regular and going to play games and hopefully game by game, practice by practice, I’ll get better, get a little more comfortable,” Sturm said today.

David Krejci, who had offseason hip surgery, is day to day. He’ll probably skate in a small group tomorrow morning before determining whether he can go through a full practice. Jamie Arniel tweaked a knee during rookie camp, so he’s day to day. Forward Lane MacDermid is also day to day with an ankle injury.

Prospect Levi Nelson suffered a broken collarbone during the rookie tournament and is out indefinitely. Another rookie, first-round pick Jordan Caron is in camp but unable to participate as he continues to recover from his collarbone injury. Goaltender Kevin Regan is still limited in his physical activity after offseason hip surgery.

•One player who played his way into an invitation to camp during the rookie tournament is 6-foot-2, 205-pound forward Jason Wilson, who skated in 52 games for the London Knights in the Ontario Hockey League last season.

“He played well,” said Chiarelli about the 19-year-old. “He’s a big, strong kid. He can still be drafted, so we’re going to take a look at him in main camp. He skates well.”

•Chiarelli wouldn’t comment on the situation with restricted free agent Phil Kessel. But one other restricted free agent not in camp is Carl Soderberg, the prospect the Bruins acquired a few years ago from St. Louis in the Hannu Toivonen trade. Soderberg has opted to continue playing in his native Sweden.

“I’ve been trying to get him over and he’s not over,” Chiarelli said.

•Julien did offer this on the Kessel holdout:

“I think our focus is really on our team. At the same time, I think Peter has done a great job of handling this situation. From the outside people can make comments. But he’s been very professional at keeping that situation in control and not having to get into a war of words, and I respect that. It’s easy to be loose-lipped and feel like you need to defense yourself, but he doesn’t. And I have full confidence that he’ll handle the situation well and the players feel that way too.”

•There are still a number of unrestricted free agents looking for work as camps open throughout the league. Some of them are interested in the Bruins, but Chiarelli’s not in a position to offer them a job as of yet.

“I’m still getting (calls). My position has been that we have a fairly full roster. We have one significant player (Kessel) unsigned and before I can really even look at doing something like that, I have to resolve that situation.”
